[Dovecot] Message Filenames
by Charlie Davis 25 Mar '06

25 Mar '06

Is there anyway to get a message's filename through the imap server? I've been developing a program for awhile and just switched to dovecot from courier. Courier had a file that for every line was like: <message uid> <message filename> Is there anway to get this information out of dovecot? -Charlie

[Dovecot] first crack at auto-trash plugin
by David Powers 25 Mar '06

25 Mar '06

I have written an alpha version of an auto trash plugin for dovecot. When compiled in any mail expunged from a non-Trash folder is moved to a folder named Trash. As of yet the folder is not created if it doesn't exist (the process fails before expunge). I would appreciate feedback of any sort. In addition, I am currently getting an error I haven't been able to puzzle out in the logs when it runs: Mar 21 15:22:01 david dovecot: imap(david(a)grayskies.net): Timeout leak: 0x807fad0 I see that it seems to relate to transactions somehow, but my few hours of playing with dovecot haven't given me the answer - so ideas/patches to the code would also be nice. You can grab it here: http://wrath.grayskies.net/tarballs/auto-trash.tar.gz -David

[Dovecot] Dovecot LDA + Fedora destribution = no go?
by Charlie Davis 25 Mar '06

25 Mar '06

Anyone know of a way to get the LDA to work on the fedora distribution available on yum? I'm a big fan of the whole yum-auto-updating thing but if this isn't possible, I'll go tarball. -Charlie

[Dovecot] Method of archiving mail?
by Stephen Allen 24 Mar '06

24 Mar '06

Hello I have a situation in which a number of users have 10,000+ messages in the maildir, going back a few years. I'm not a fan of this many files lying around so I'd like to set up some kind of archiving, but one that will allow user's access to the old mails should they wish to see them. I thought of a cron job trying to sift through messages pulling those what were older than x days, then writing some script to process a request from a user (date/time/from/to/subject/body text) and copy matching messages to a "query" folder in the maildir. However, a) I'm not good at this kind of thing, and b) I have a feeling it's already been done before. Can anyone point me in the right direction please... is their software around to do this already? Many thanks, Steve :)

[Dovecot] Imap Timeouts
by Neil Wilson 24 Mar '06

24 Mar '06

Hi guys, I've got a client running 1.0.beta3 on SuSe 9.3 Everything has been running perfectly since it was installed about 6 months ago, but lately they've had issues with email clients not being able to connect to the IMAP server, until they close their clients(Thunderbird & Outlook) and then re-open them. They have roughly 70 users on their network, so it sounds like it could be too many active sessions at once, but I've tried changing a few things in the config, and so far nothing has resolved this. Any help would be appreciated. Regards.

[Dovecot] Can Dovecot 'slurp' into the INBOX from a mail spool file?
by Daniel Watts 23 Mar '06

23 Mar '06

Hi guys, I have a system whereby I am forced to deal with mbox files of /var/spool/mail/user1 (mbox text file) /var/spool/mail/user2 (mbox text file) etc Their mail homes are maildir format in: /home/user1/Maildir/{cur,new,tmp} /home/user2/Maildir/{cur,new,tmp} etc I can set things up so that the mbox inbox is shown using namespaces: namespace private { separator = / prefix = location = maildir:/home/virtual/%d/home/%n/Maildir/ } namespace private { separator = / prefix = mail/ inbox = yes hidden = no location = mbox:/home/virtual/%d/home/%n/mail/:INBOX=/home/virtual/%d/var/spool/mail/%n } This gives a rather odd folder structure as follows: INBOX Sent Drafts Trash mail/ --- INBOX myfolder1 myfolder2 Both of those INBOXes are actually the same folder. I'd ideally like to hide the mbox namespace entirely so that the user does not see any mbox folders. UW IMAP, with it's mbx format, allows you to just drop in a file called INBOX in mbx format and it will 'slurp' the /var/spool/mail/usersmbox file into the mbx INBOX. Has/could Dovecot have a similar feature whereby you specify a spool folder which is then 'slurped' into the local maildir INBOX? Not sure if I'm being clear enough here - do let me know if not! Much thanks, Daniel

[Dovecot] Losing messages
by Stian Jordet 23 Mar '06

23 Mar '06

Hi, I have been running dovecot cvs happily for.. well.. very, very long now. Don't remember when I switched from 0.99, but it was back in the test-days, long before the alpha's. Anyway, it seems to have been working very well all the time. But recently three of my clients have claimed to have lost mail when moving from Thunderbird. I even experienced it myself once. I'm using Evolution 99% of the time, and have never seen any problems with that - but that doesn't mean the problem only occurs with Thunderbird. When moving mail from one folder to another, everything seems fine, except that the mail isn't in any folder anymore. It _seems_ related to this: Mar 14 14:46:53 buick dovecot: imap(larsmj): Fixed index file /home/larsmj/Maildir/.Junk/dovecot.index: first_recent_uid_lowwater 40 -> 36 Mar 14 14:46:53 buick dovecot: imap(larsmj): Corrupted index file /home/larsmj/Maildir/.Junk/dovecot.index: Duplicate header extension keywords But I'm not sure. Either way I get these lines rather often for some users. What does it mean? Anyone seen anything like it? I really don't like the idea of losing clients mail... I hope someone can shed some light on this. Best regards, Stian

RE: [Dovecot] Shared namespaces - solved

Hi Steffen, I'm using procmail as my LDA and postfix as my MTA. Also, in my case I need all email to any email address at my domain starting with "pr" then some numbers to go into these folders. The reason for this is I'm trying to setup an open-source replacement for our mail-enabled Exchange Public Folders at the moment (can you believe you can't search sub-folders in Exchange Public Folders?!). First I created a fake user with it's own group: adduser public_folders Next, I added all the relevant users to that group: usermod -G public_folders john_smith usermod -G public_folders jon_doe Next, in /home/public_user/.procmailrc I put the following: MAILDIR=/home/public_folders/Maildir # If any mail gets through to this account without having a project number address, # put it in an "Unfiled" folder. DEFAULT=$MAILDIR/.Unfiled/new * # This line just gets me the project number (also makes sure the preceding letters * # are uppercase - otherwise we could end up with separate folders for pr123, Pr123, * # pR123 and PR123. * PROJECT_NUM=`formail -xTo: | egrep -o [pP][rR][0-9]+ | tr '[a-z]' '[A-Z]'` # This is not absolutely necessary, but I prefer to keep logs so I can see where # emails have been stored if anything goes missing. LOGFILE=$MAILDIR/procmail.log # This UMASK setting is basically what you're looking for, Steffen. The mail files # on the disk are stored with mode 660. UMASK=007 # Because these are public folders receiving a lot of mail, I've put in a big message # ID cache. :0 Wh: msgid.log |formail -D 2097152 $MAILDIR/msgid.cache * # Notice that regexps in .procmailrc are case insensitive unless you specify otherwise * :0 H * * ^To: .*PR[0-9]+(a)mydomain\.tld * { * PROJECT_FOLDER=$MAILDIR/.Projects.${PROJECT_NUM} * * # Here I basically check if the folder exists. If not it's created with mode * # 770 - this is also important. * :0 Wic: * * ? test ! -d ${PROJECT_FOLDER} * # Make all the subfolders, or they will be made by dovecot when the first user * # tries to look in there messing up the permissions on that folder. * |mkdir -m 770 -p ${PROJECT_FOLDER}/new;\ * mkdir -m 770 ${PROJECT_FOLDER}/cur;\ * mkdir -m 770 ${PROJECT_FOLDER}/tmp * * # And here I finally store the email * :0: * ${PROJECT_FOLDER} * } Make sure the file has mode 0600 public_folders:public_folders or procmail will ignore it. Next, I had to set the following permission on the public_folders home folder: chmod 770 /home/public_folders Next, I put the following namespace into /usr/local/etc/dovecot.conf: namespace public { separator = / prefix = Public/ location = maildir:/home/public_folders/Maildir:INDEX=%h/Maildir/public_folders/indexes:CONTROL=%h/Maildir/public_folders/control inbox = no hidden = no } Next, I made sure the relevant folder structure existed with the right permissions (I cheated and did this as root): cd /home/public_folders mkdir -p Maildir/new cd Maildir mkdir cur mkdir tmp mkdir -p .Unfiled/new mkdir .Unfiled/cur mkdir .Unfiled/tmp for file in `find`; do chown public_folders:public_folders $file if [ -d $file ]; then chmod 770 $file else chmod 660 $file fi done *Next, I made a file called /etc/postfix/virtual.pcre with the following content: * * /^[pP][rR][0-9]+(a)mydomain\.tld/ public_folders@localhost * *And finally I put the following into /etc/postfix/main.cf: * * virtual_alias_maps = pcre:/etc/postfix/virtual.pcre, hash:/etc/postfix/virtual Then I restarted postfix and away I went. Now when someone sends an email to "pr123(a)mydomain.tld" it gets put into the relevant project folder under the "public _folders" maildir. If you don't need the automated project filing, ignore the lines with a * at the start. I hope someone finds this helpful.
